“…The compressive stress, on the other hand, has been shown to cause switching of ferroelastic domains in PZT in direction orthogonal to the loading axis. 39 Similar behavior was observed in BaTiO 3 single crystals under compressive stress, in which 90°(a−c domains) domain switching involving nucleation and expansion of c-domains takes place, in addition to the formation of surface confined sawtooth 180°a-domains (to compensate surface charges). 24 In near-morphotropic PZT ceramics consisting of randomly oriented crystallites, a variety of ferroelastic domain evolution processes were recorded such as expansion/contraction of stripe domains, rotation of stripes domains by 90°, coalescence of needle domains with orthogonal stripe domains forming herringbone-like domain structure, and wall motion in herringbone-like domains under an applied compressive load.…”

We investigate the effect of variable uniaxial tensile strain on the evolution of 71° ferroelastic domains in (001)-oriented epitaxial BiFeO (BFO) thin films using piezoresponse force microscopy (PFM). For this purpose, a newly designed bending stage has been employed, which allows tensile bending as wells as in situ PFM characterization. In situ PFM imaging reveals polarization-strain correlations at the nanoscale. Specifically, ferroelastic domains with in-plane polarization along the direction of applied tensile strain expand, whereas the adjoining domains with orthogonal in-plane polarization contract. The switching is mediated by significant domain wall roughening and opposite displacement of the successive walls. Further, the domains with long-range order are more susceptible to an applied external mechanical stimulus compared to the domains, which exhibit short-range periodicity. In addition, the imprint state of film reverses direction under applied tensile strain. Finally, the strain-induced changes in the domain structure and wall motion are fully reversible and revert to their as-grown state upon release of the applied stress. The strain-induced non-180° polarization rotation constitutes a route to control connected functionalities, such as magnetism, via coupled in-plane rotation of the magnetic plane in multiferroic BFO thin films.

“…indicate the compositions of the enriched clusters . These composition ratios correspond to the tetragonal and rhombohedral phase fields on either side of the MPB, suggesting that changes in the crystal structure might exist and lattice strains could arise from the differences . This information may be used in the future to correlate the domain structure of ferroelectric oxides.…”

Atom probe tomography (APT) is a powerful materials characterization technique capable of ppm chemical resolution and near atomic scale spatial resolution. However, owing to a number of factors, the technique has not been widely applied to insulating materials and even less to complex oxides. In this study, we outline the methodology necessary to obtain high‐quality results on a technologically relevant complex oxide Pb(Zr,Ti)O3 (or PZT) using laser‐assisted APT on both bulk and thin film specimens. We show how, with optimized and well‐controlled conditions, APT complements conventional techniques such as STEM‐EDS. The correlative information can be used to obtain the nanoscale 3‐D chemical information and investigate the nanoscale distribution of cations. Using nearest‐neighbor cluster analysis routines, 5–10 nm segregation of B‐site cations was detected in bulk sintered PZT 53/47 from chemically prepared powders. No statistically significant segregation of B‐site cations was observed in thin film specimens. This work opens new avenues toward understanding the process‐structure properties in complex materials at length scales heretofore unachievable.

“…It is well known that nonlinear dependence of stress on strain for dense PZT ceramics is due to stress-induced domain switching process (Schäufele et al, 1996;Forrester and Kisi, 2004;Jones et al, 2007;Okayasu et al, 2011). Nevertheless, for porous PZT95/5 ceramics, the stress-strain curves as shown in Fig.…”

A series of uniaxial compression experiments on unpoled porous lead zirconate titanate Pb(Zr0.95Ti0.05)O3 (PZT95/5) ceramics were performed to investigate the influence of porosity on the mechanical properties, domain switching and phase transformation via non-contact digital image correlation optical technique to measure the full-field strain. Four unpoled PZT95/5 ceramics were fabricated with a range of porosity levels via systematic additions of pore formers. The nonlinear compressive mechanical behaviors of unpoled PZT95/5 ceramics were measured and evaluated as a function of porosity. The nonlinear deformation mechanism of unpoled PZT95/5 ceramics was attributed to domain switching and ferroelectric (FE) to antiferroelectric (AFE) phase transformation processes, which was verified by analyzing the anomalous behavior between axial strain and radial strain. Normalized critical stresses for the onset of domain switching as well as the onset and exhaustion of phase transformation resulted in a very similar linear decrease with increasing porosity. We suggest that a critical macroscopic volumetric strain is needed for the onset of phase transformation that is nearly independent of porosity.
